OF CHICAGO, ILLI- DUMP-'CAFL SPECIFICATION forming part of LettersPatent No. 764,355, dated July 5, 1904.

[Implication filed July 11, 1903.

To all whoiit t 'n1/(ty concern.'

Be it known that we, HARRY StriLLsoNl-IART and O'ino l/V. MuissNEu,citizens oi' the United States, residing at Chicago, in the county ofCook and State oi Illinois, have invented certain new and usefulImprovements in Dump- Cars, oi' which the following is a specification.

cars-all of which will more fully hereinafter appear.

The principal object of the invention is to provide a simple,economical, and eilcient convertible dump-car.

Further objects oiy the invention will appear from an examination oi'the drawings and the following' description and claims.

The invention consists principally in a convei'tible d ump-car in whichthere are combined a supporting-framework provided with downwardly andoutwardly extending side discharging-aprons, side boards pivotall ysecured longitudinal center, and swinging upper portions fulcrumed inthe traine of the cai' and adapted to be moved to a position where theyinclineupwardly and outwardly to form the upper inclined portions of theV-shaped hoppei' and to be folded upwardly and inwardly into a secondposition to form, in connection struction hereinafter described andclaimed.

In the accompanying drawings, Figure l is Serial No. 165.199. (Nomodel.)

it appears when constructed in accordance with these improvements; Fig'.4, a cross-sectional view ot the cai', showingI the lvarious 50 across-sectional elevation showing' the parts S 5 arranged to form aHat-bottom gondola car.

In illustrating and describing these iinprovements we haveonly-illustrated and will describe that which we consider to be new,

taken in connection with so much as is old as GO will properly disclosethe invention to others and enable those skilled in the ai't to practicethe same, leaving' out of consideration otliei' and well-known .elementswhich, it set forth herein, would only tend to confusion, pro-65 lixity,and ambiguity.

In constructing a cai' in accordance with these improvements we providea supporting'- Iframework which has a discherging-apron (t inclineddownwardly and oiitwardly at each 70 side from end to end oit' the car.This supporting-fi'ainework has also a V-shaped'hopper portionformed ofone'iixed section and a swinging section c, arranged lengthwise olf n 1l` the car and with its apex at er near the lon'- 75 g'itudinal centerand between the` car-trucks only, as shown particulai'lyin Fig'. 2."This supporting-framework is iiii'ther provided with a pair ollongitudinal sills (l, one et' which is arranged intermediate theV-shaped SO hopper and each discharging'-apron, to the frame portions ofwhich they are connected by means of brace-rods c, which' lead therefromto the diseliarging-api'ons. A second set of bi'acc-rodsf leads fromsaid interme- S5 diate sills to the framework o'l.E the V-shaped hopperportion. A plurality oliupwardlyextending' side posts g is provided,attached at their loweredg'es, by means el gusset-plates p /t andbrace-rods '/I, to the frame ot' the dis-1h90 charging-aimons andconnected together in'an a side elevation oi' one end of a car as itappears when constructed in accordance with these improvements; Fig. 2,a perspective detail of the angular locking-bar hereinafter` described;Fig. 3, an end view of the caras efficient manner at or near their upperedges by means of channel-beamsy', which extend i the entire length ol'the car. To these upper channel-beams are pivotally connected sideboards It', formed of a plurality of swinging sections, having theirlower free edges arranged to be brought into meeting contact with theouter lateral edges of the discharging-aprons and form in connectiontherewith a side-dumping car and in connection with the V-shaped hoppera combined side and center dump car.

To operate the swinging section which forms a discharging-door for theV-shaped hopper, the usual rock-shaft Zand chain mechanism mare providedand connected with such swinging section in the usual and ordinarymanner. To lock the swinging side boards, however, an improved mechanismmust be provided, and for this purpose we provide locking angle-bars at,one of which is arranged at or near each side of-the car and by means ofswinging L-bars o are pivotally secured to the supporting-framework ofthe car. Each of these L-bars-and there are several at each side of thecar-have one portion forming a curved projecting linger p, which whilethe parts are being swung to their locking posi- A tion, as hereinafterdescribed, will iirst contact the lower edges of the swinging sideboards before they are quite closed and force them into closed position,when the anglebars, as shown particularly in Figs. 5 and 6, will finallyContact and hold the doors closed in vertical position and at the sametime form a seal to prevent discharge of comminuted material. To operatethese locking anglebars as desired, a rock-shaft q is rotatably mountedin bearings at or near the upper edge of each side of the car andprovided with chain and rod mechanism r, connected with eye-bars s onthe angle-bars, so that as such rock-shafts are rotated in one directionthe angle-bars, with their closing-fingers, are moved toward lockingposition, while during the ro- -tation of the rock-shaft in vtheopposite direction they are permitted to drop into the poi sition shownin Fig. Lto allow the side doors to be opened.

To form the convertible means,a pair of upper swinging sections t isprovided and arranged so that they may be moved into one position, (seeFig. 5,) where they form the upper inclined portions of the V-shapedhopper, and into a second position, (see Fig. 4,)

where they, form the upper inclined portionsl -of (and in connectionwith the dischargingaprons) an A-shaped side-dumping bottom. It isdesirable to provide means for fulcruming and holding these upperswinging' sections in their diferent positions. In order position to theLipper edges of the discharging-aprons, which form the fulcrum-blocksfor the upper swinging sections when the same are arranged in theirA-shaped position. These upper swinging sections extend from end to endof the car, and it is very desirable to provide some means to hold themin their A-shaped position; otherwise a heavy load in the car of coal,sand, rock, or the like might tend to displace them. To provide suchmeans, removable end boards are provided, one at each end of the car,having' outer end stakes y, the lower ends of which are arranged to restin metal pockets 2. The inner faces of these removable end boards areprovided with inwardly-extending cleats 10, arranged in an A- shapedmanner, so that they contact the ends of the upper swinging sections andprevent them from being displaced when the car is being loaded or in,fact at, any time until the end boards are removed. It will beunderstood, of course, that it is necessary to remove theseend boardsbefore the upper swinging sections can be moved from or into their A-shaped position. In Fig. 6 we have shown these upper swinging sectionsarranged in a third position-viz., a position in which they form theflat bottom of a gondola car, and in order to hold them in such positionthe upper edges of such swinging sections are provided with angle-blocksll, adapted to engage with a U-shaped locking-bar 12 at or near cach endof the car. Vhen the parts are in this position, as shown in Fig. 6, themeeting edges of the movable sections are locked in such U-shaped blockand held against lateral displacement.
